TL;DR: In this article, the authors quantified the significant environmental aspects of a new high-end office building over 50 years of service life and found that most of the impacts are associated with electricity use and building materials manufacturing.
Abstract: This paper quantifies the significant environmental aspects of a new high-end office building over 50 years of service life A comprehensive environmental life-cycle assessment—including data quality assessment—was conducted to provide detailed information for establishing the causal connection between the different life-cycle elements and potential environmental impacts The results show that most of the impacts are associated with electricity use and building materials manufacturing—in particular, electricity used in lighting, HVAC systems, and outlets; heat conduction through the structures; manufacturing and maintenance of steel; manufacturing of concrete and paint; water use and wastewater generation; and office waste management Construction and demolition were found to have relatively insignificant impacts The identified most significant aspects are quite predominant; 7% of all counted aspects cover over 50% of the life-cycle impacts Practical applications of the study’s results could be in the e

TL;DR: This article estimates the changes in parameters of the Tonle Sap flood pulse due to the flow alterations in the Mekong River and the impacts on the flooded area and loss of gallery forest and protected areas were analyzed using geographic information system–based methods.
Abstract: Rapid development in the upper reaches of the Mekong River, in the form of construction of large hydropower dams and reservoirs, large irrigation schemes, and rapid urban development, is putting water resources under stress. Recent studies have concluded that these developments will lead to flow alterations in the Mekong River. These flow alterations would threaten the sensitive ecosystems downstream, particularly Tonle Sap River, Tonle Sap Lake, its floodplain, and its gallery forest and protected areas, by changing the flood-pulse system of the lake. This article estimates the changes in parameters of the Tonle Sap flood pulse due to the aforementioned flow alterations. The impacts on the flooded area and loss of gallery forest and protected areas were analyzed using geographic information system–based methods. Relatively small rises in the dry-season lake water level would permanently inundate disproportionately large areas of floodplain, rendering it inaccessible to floodplain vegetation and eroding the productivity basis of the ecosystem. It is highly important to maintain the natural hydrological pattern of the Mekong River, particularly the dry-season water levels, to preserve Tonle Sap Lake’s ecosystem productivity.

TL;DR: The first observation of 15 voltammetric quantized charging peaks for a solution of hexanethiol-capped gold nanoparticles (so-called monolayer protected clusters MPCs) at room temperature is reported where the variation in peak spacing with increasing charge stored in the metal core is discussed in terms of MPC capacitance.

TL;DR: In this article, a measurement of the cosmic ray positron fraction in the energy range of 1 −30 GeV was presented, based on data taken by the AMS-01 experiment during its 10-day Space Shuttle flight in June 1998.
